  1. 3. the property that states that numbers can be added or multiplied in any order and achieve the same result
  2. 4. to distribute or combine all like terms in order to reduce the complexity of an expression
  3. 5. An equation that is unsolvable, because the variables cancel each other and no value will make it balanced. Ex: 4x+5=4x+8; 5=8
  4. 8. An equation with multiple variables.
  5. 10. the answer to a subtraction problem.
  6. 12. a number that is being added or subtracted in an expression or equation; will always stand alone
  7. 13. a letter in an equation or inequality that represents an unknown number
  8. 14. All real numbers are solutions because both sides of the equation are the same and any value will make it balanced. Ex: 2x+5=2x+5
  9. 15. the answer to a multiplication problem.
  10. 18. a grouping of numbers, variables, and operations without an equal sign; can be evaluated and simplified
Down
  1. 1. a grouping of numbers, variables, and operations with an equal sign; can be solved
  2. 2. the answer to a division problem.
  3. 6. A pair of numbers that equal zero when combined. Ex: 3 & -3; 9 & -9
  4. 7. using opposite operations to cancel out coefficients and constants in equations and inequalities to isolate the variable; Ex: addition & subtraction
  5. 9. the property that allows you to multiply a number outside a set of parentheses with each number or term within the parentheses
  6. 11. a number multiplied by a variable; is always in front of a variable
  7. 16. parts of an expression or equation, which are separated by addition and subtraction that have the same variable and exponent
  8. 17. There is only one solution to the equation that will make it balanced. Ex: x = 4
  9. 19. the answer to an addition problem.
  10. 20. positive and negative whole numbers, as well as zero. Ex: -2, -1, 0, 1, 2
